About this game

ThinkGrid is a calm collection of logic puzzles for people who want to think, not be sold to.

Ten hand-crafted puzzle types in one quiet app. No ads. Ever. No coins, no timers counting down, no popups asking you to buy something at the exact moment you got stuck.
Just puzzles, and the slow pleasure of working one out.
